Covalent compounds: Polarity and Intermolecular forces (notes will be completed on Monday)
  • Important note: On page two, the first bullet point under the "Intermolecular forces" section, should start with "Intermolecular forces: " instead of "Intramolecular forces":


(NEW!!!) Video on intermolecular forces:

Completed Lesson 9 notes on polarity and intermolecular forces



Ionic compounds

*Note: Na+ has a smaller atomic radius than Cl- (look at the electron configuration). Therefore the smaller "sphere" in the NaCl 3D structure in the notes should be labelled as Na+ and the bigger "sphere" should be labelled Cl-.

Worksheet Solution
  • Updated: Question 2 c)
  • Mistake in Question 3a) The strongest intermolecular force present is hydrogen bonding
